Hello,
tried to follow Kaj's suggestion, but it doesn't work in my case ...
I've also tried to "manually" kill jack (using terminal) as Jean suggested;
in this case the audio of other app start working again but if open
aHydrogen a second time (starting Qjackctl first) hydrogen has no sound
even if qjackclt told me server is running.
What's wrong?
Sorry, I know my questions may sound too noobish for you, but I'm quite new
in ubuntu-studio.
Thanks again for suggestions (and patience) and further help in advance
Regards
PS: Maybe the problem is also I've not yet realized how server audio works
on linux (I come from windows and this kind of things are a lot simple from
a user point of view) is there any sort of step by step guide to better
understand this topic, maybe there is no issue in my case and I'm messing
around everithing ... :-)
